Diagnostic value sperm function tests routine semen analyses fertile infertile men
2009/2/23
The results of routine semen analyses, the zona-free hamster oocyte penetration test, the hypoosmotic swelling test, and semen adenosine triphosphate levels were studied in 66 fertile and 130 infe...
Male fertility and positive Chlamydial serology. A study of 61 fertile and 82 subfertile men
Male fertility positive Chlamydial serology 61 fertile 82 subfertile men
2009/2/23
In this study, the frequency and titers of serum antibodies to Chlamydia trachomatis in fertile and subfertile subjects and possible correlations between a positive serology and the values of conven...
Possible significance of transferrin levels in seminal plasma of fertile and infertile men
seminal transferrin FSH fertility man
2009/2/23
Human seminal plasma contains large amounts of transferrin, which is a protein secreted mostly by Sertoli cells. It has been suggested that the concentration of transferrin may serve as a possible c...
Cytoplasmic estradiol binding sites in testis of fertile and infertile men
estradiol receptors human testis receptor ontogenesis Leydig cell function human testicular disorders testicular cytosolic receptors
2009/2/20
Free cytoplasmic estradiol receptor was determined in testicular biopsies from six adults showing various primary testicular disorders, and in testicular tissue obtained at autopsy from 18 males of ...
Reproductive history and semen analysis in prevasectomy fertile men with and without varicocele
varicocele reproductive history fertile men semen analysis
2009/2/20
A group of 598 allegedly fertile men requesting vasectomy were investigated; varicocele was found in 97 (16.2%) of these men. The mean ages and age distributions of men with and without varicocele w...
Heterologous ovum penetration test and seminal parameters in fertile and infertile men
Heterologous ovum penetration test seminal parameters fertile infertile men
2009/2/19
Sperm penetration rates in the heterologous ovum penetration test were correlated with results of routine semen analysis in 30 fertile and 50 infertile men. There was no difference in penetration ra...
Presence and modulation of interleukin-12 in seminal plasma of fertile and infertile men
Cytokines interleukins infertility semen
2009/2/17
Interleukin-12 (IL-12) is a unique cytokine that recently has drawn considerable attention because of its immunomodulatory properties and its possible involvement in several normal physiological a...
HCG binding to the testicular LH receptor is similar in fertile, subfertile, and infertile stallions
Fertility horses testis
2009/2/17
Recent evidence in our laboratory suggests that the cause of idiopathic subfertility/infertility in breeding stallions may originate in the testes at the luteinizing hormone (LH) receptor or postr...
Capacitation in vitro of stallion spermatozoa：comparison of progesterone-induced acrosome reactions in fertile and subfertile males
Equine male gamete infertility acrosomal
2009/2/13
Mammalian sperm that have completed capacitation are capable of undergoing the acrosome reaction in response to a number of biological and chemical stimuli. In the present report, we have investig...
The nuclear status of human sperm cells by TEM image cytometry：nuclear shape and chromatin texture in semen samples from fertile and infertile men
human sperm cells TEM image cytometry nuclear shape chromatin texture semen samples
2009/2/12
Changes in nuclear size, shape, and chromatin texture during spermiogenesis and epididymal transport of human sperm were recently analyzed using transmission electron microscopy (TEM) image cytome...
Human sperm acrosin. Further studies with the clinical assay and activity in a group of presumably fertile men
spermatozoa acrosin Triton X-100 fertility
2009/2/11
The goals of this study were to determine the effect of the nonionic detergent, Triton X-100, on the recovery of acrosin in the clinical assay (Kennedy et al, 1989), since previous investigations ...
